Horseshoe kidney is a rare congenital anomaly showing various degrees of fusion and accessory blood supply. Coexistence of horseshoe kidney and aortic aneurysm therefore presents a technical challenge to vascular surgeons. We report an 83-year-old woman with a ruptured abdominal aortic aneurysm associated with horseshoe kidney. Preoperative computed(More)
Juvenile xanthogranuloma is usually a self-limiting disease of the skin. Intracranial manifestations are extremely rare. We report the clinico-pathological features of an 8-month-old boy suffering from a gradually enlarging nodule of the chest wall and subsequent epileptic seizures. The subcutaneous tumor and a cerebral subcortical tumor of the left(More)
OBJECTIVE Hypoxic perfusion before arrest, an indeterminate period of warm ischemia, and subsequent reperfusion are major causes of cardiac allograft dysfunction in non-heart-beating donors (NHBDs). The present study was undertaken to elucidate the cardioprotective effects of ET(A) receptor antagonist FR139317 for hearts obtained from asphyxiated NHBDs in a(More)
Surgical treatment of aortic regurgitation due to Behçet's disease is difficult. A 57-year-old male with Behçet's disease underwent aortic valve replacement with a mechanical valve for aortic regurgitation in 1995. Due to prosthetic valve detachment, 5 months thereafter he underwent a Bentall type operation with a composite graft. Due to complication of the(More)
OBJECTIVE Open-heart surgery without homologous blood transfusion is still difficult in children because priming volume in cardiopulmonary bypass circuit results in extreme hemodilution. Vacuum-assisted cardiopulmonary bypass circuit has the benefit of improving venous return and results in lowering priming volume. We introduced vacuum-assisted(More)
BACKGROUND It is known that denervation occurs in the regions of myocardium treated by laser transmyocardial revascularization (TMR). The purpose of this study was to determine when regional denervation occurs in the early postoperative period and whether or not it is specific to laser TMR when compared with TMR using ultrasonically activated energy.

For 13 years between 1980 and 1992, 23 patients needed pacemaker (PM) implantation because of bradyarrhythmia, 21 of atrial fibrillation and two of complete A-V block, after valve surgery. Five of 88 survivors (5.7%) after OMC, 11 of 227 (4.8%) after MVR, one of 169 (0.6%) after AVR, five of 67 (7.4%) after MVR + AVR and one of 15 (6.7%) after TVR underwent(More)
OBJECTIVES Open heart surgery without homologous blood transfusion remains difficult in children. The introduction of vacuum-assisted cardiopulmonary bypass circuits to reduce priming volume for pediatric patients has improved the percentage of transfusion-free operations. We retrospectively analyzed blood transfusion risk factors to further reduce blood(More)
In elderly patients, open surgery for patent ductus arteriosus (PDA) is more difficult than that in children and often requires a cardiopulmonary bypass. We report the case of a 67-year-old patient with a PDA that was successfully treated with thoracic endovascular aortic repair (TEVAR). The patient was diagnosed with congestive heart failure (ejection(More)
